Re: Can scientists 'make' red blood cells, white cells, or any other cells?

At this point, what you have proposed is not feasible.  Scientists cannot 
make blood cells from organic molecules.  While it might be more feasible to 
try this with red blood cells (because they have no nucleus at that stage of 
development), all other blood cells do have a nucleus.  Not only do we need 
to know the atomic structure of the cell, but also the genetic blueprints.  
Synthesizing an entire genome to create a synthetic cell would not be 
financially feasible, even if theoretically possible.

However, with the advent of stem cell research, scientists have been able to 
grow blood cells from undifferentiated stem cells.  A stem cell has the 
potential to become many different types of cells.  Scientists have been 
able to figure out what conditions (growth factors and other nutrients) are 
required for growing red blood cells and certain types of white blood cells.

The cells generated by stem cell technology are "made" in the lab, but they 
are still derived from living cells.
